One of the things I found out when I had right rotator cuff surgery is that these work injuries occur on the opposite of your dominate handedness.
I’m mostly ambidextrous. I write, play racquet sports, brush teeth, fork, left handed. I throw, play golf, cut meat, play guitar right handed. Sleep on my right side when not on my back. Mouse right handed. Trackball left handed. I play darts either but prefer left handed. Scissors I have adapted to a right hand world, lol, I guess in a lot of subtle ways. I hold a book when reading in my left hand. Prefer jewelry bracelets on my left wrist.
I never realized how right shouldered I was until surgery. Can’t use a purse or backpack on my left shoulder.
I guess we all have a preferred side for everything. Was very interesting to realize this about myself.
